基础用法

圆角

使用 rounded-smroundedrounded-lg 等实用程序将不同的边框半径大小应用于元素。

rounded

rounded-md

rounded-lg

rounded-full

<div class="rounded ..."></div>
<div class="rounded-md ..."></div>
<div class="rounded-lg ..."></div>
<div class="rounded-full ..."></div>

药丸按钮

使用 rounded-full 实用程序创建药丸按钮。

rounded-full

<button class="rounded-full ...">Save Changes</button>

无圆角

使用 rounded-none 从元素中删除现有的边框半径。

rounded-none

<button class="rounded-none ...">Save Changes</button>

这最常用于删除在较小断点处应用的边框半径。

分别对边进行圆化

使用 rounded-t-*rounded-r-*rounded-b-*rounded-l-* 实用程序仅对元素的一侧进行圆化。

rounded-t-lg

rounded-r-lg

rounded-b-lg

rounded-l-lg

<div class="rounded-t-lg ..."></div>
<div class="rounded-r-lg ..."></div>
<div class="rounded-b-lg ..."></div>
<div class="rounded-l-lg ..."></div>

单独圆角

使用 rounded-tl-*rounded-tr-*rounded-br-*rounded-bl-* 实用程序仅将元素的一个角弄圆。

rounded-tl-lg

rounded-tr-lg

rounded-br-lg

rounded-bl-lg

<div class="rounded-tl-lg ..."></div>
<div class="rounded-tr-lg ..."></div>
<div class="rounded-br-lg ..."></div>
<div class="rounded-bl-lg ..."></div>

使用逻辑属性

使用 rounded-s-*rounded-e-*rounded-ss-*rounded-se-*rounded-es-*rounded-ee-* 实用程序通过 logical properties 设置边框半径,这些半径根据文本方向映射到适当的角。

Left-to-right

Right-to-left

<div dir="ltr">
  <div class="rounded-s-lg ..."></div>
<div>

<div dir="rtl">
  <div class="rounded-s-lg ..."></div>
<div>

这里列出了 LTR 和 RTL 模式下所有可用的边框颜色逻辑属性实用程序及其物理属性等效项。

ClassLeft-to-rightRight-to-left
rounded-s-*rounded-l-*rounded-r-*
rounded-e-*rounded-r-*rounded-l-*
rounded-ss-*rounded-tl-*rounded-tr-*
rounded-se-*rounded-tr-*rounded-tl-*
rounded-es-*rounded-bl-*rounded-br-*
rounded-ee-*rounded-br-*rounded-bl-*

为了获得更多控制,您还可以使用 LTR and RTL modifiers 根据当前文本方向有条件地应用特定样式。


有条件申请

悬停、聚焦和其他状态

Tailwind 允许您使用变体修饰符有条件地在不同状态下应用实用程序类。例如,使用 hover:rounded-lg 来仅 在 hover应用 rounded-lg.

<div class="rounded hover:rounded-lg">
  <!-- ... -->
</div>

详细了解, 请参考 Hover, Focus, & Other States 文档.

断点和媒体查询

您还可以使用变体修饰符来定位媒体查询,例如响应式断点、暗模式、首选减少运动等。例如, 使用 md:rounded-lg 来应用 rounded-lg 程序,适用于中等屏幕尺寸及以上。

<div class="rounded md:rounded-lg">
  <!-- ... -->
</div>

进一步了解,请参考 响应式设计, 暗黑模式 媒体查询.


使用自定义值

定制你的主题

默认情况下,Tailwind 提供五种边框半径大小实用程序。您可以通过编辑 Tailwind 配置的 theme.borderRadius 部分来更改、添加或删除这些实用程序。

tailwind.config.js
module.exports = {
  theme: {
    borderRadius: {
      'none': '0',
      'sm': '0.125rem',
      DEFAULT: '0.25rem',
      DEFAULT: '4px',
      'md': '0.375rem',
      'lg': '0.5rem',
      'full': '9999px',
      'large': '12px',
    }
  }
}

theme customization 文档中了解有关自定义默认主题的更多信息。

任意值

如果您需要使用一次性的 border-radius值,而该值没有必要包含在主题中,请使用方括号动态生成属性,使用任意值。

<div class="rounded-[12px]">
  <!-- ... -->
</div>

进一步了解,请参考 任意值 文档.
